An amnesiac girl who was roped into participating in the "killing school trip" set in the Isle of Nowhere. Perhaps due to her desire to find her memories, Sora is a very curious girl with a somewhat blunt way of speaking. Even with this way of talking, Sora cares a great amount for her friends, and is seen trying to calm them down quite a bit. Underneath her cold exterior, she can be very anxious at times.
